pdfbox库的PDTextField.setValue方法报错，怎么处理？


for (PDField field : acroForm.getFields()) {
                System.out.println(field.getFullyQualifiedName());
                if (field instanceof PDTextField) {
//                    field.getWidgets().get(0).setHidden(false);
                    field.setValue("123");
                    System .out.println(
                            "First Name=" + field.getValueAsString() );
//                    field.setValue(field.getFullyQualifiedName());
                }
            }
